That is what is triggering it.
The IRS says to use (a) the Iterative calculation, (b) the alternative calculation or (c) any reasonable method.
TurboTax uses the Iterative calculation, which usually makes the most sense.
Unfortunately, sometimes the Iterative calculation doesn't really work out completely (and may need to resort to the alternative calculation). When that happens, the math calculation doesn't fully account for the amounts and ends up with a 'remainder' amount that TurboTax does know what to do with, so it throws it on Schedule A as a medical deduction.
I haven't checked for while, but in previous years there was also a glitch that 'stopped' the calculation from completing, which resulted in the odd 'remainder' amount when it wasn't necessary.
Using those special methods the program is often correct. But because it ends up with the weird 'remainder' amount, you should probably use the "any reasonable method" rather than the specific methods.
For any 'missing'/remainder amount, you may consider it "reasonable" to enter it directly as a non-ACA insurance expense where the program asks for it.
